Hose > Tube Adpt.

The Hose to Tube Adapter from EARLS is a precision straight fitting designed to seamlessly connect hydraulic and pneumatic lines in high-performance applications. Built for professionals who demand reliable connections in automotive, marine, and industrial systems, this adapter bridges 10mm hose connections to 3 AN male threads without leaks or pressure loss. The compact design and minimal weight make it ideal for tight engine bays, custom fabrication projects, and system modifications where space and reliability are non-negotiable.

Manufactured from steel and finished with zinc plating, this straight adapter features a 10mm inverted flare female port on one end and a 3 AN male port on the other, ensuring robust sealing and corrosion resistance in demanding environments. The inverted flare design creates a positive mechanical lock that prevents separation under vibration and pressure cycling, critical for brake lines, fuel systems, and coolant circuits. Zinc plating protects against oxidation while maintaining conductivity for grounding applications. The straight configuration eliminates flow restrictions and simplifies installation in linear routing scenarios.

This adapter suits builders working with AN-spec hydraulic systems, restorers upgrading aging hose assemblies, and engineers designing custom fluid transfer networks. The 1.00 inverted flare female thread accommodates standard 10mm hose barbs and fittings, while the 3 AN male end pairs with any component featuring AN3 ports—carburetors, fuel rails, dampers, and power steering components. Installation requires standard wrenches and basic thread-sealant protocol; the compact 3-inch length ensures fitment in congested engine compartments without additional adapters.
